In Voltaire's article Freedom in a Philosophical Dictionary, he said: Freedom is "the power to try to do what your opinion absolutely requires". In his view, freedom is a natural right that everyone enjoys. He greatly appreciates Britain's freedom under the constitutional monarchy. First of all, the British have "all personal and property freedom", freedom of belief, "everyone can worship God in his own way", "freedom to put forward opinions to the country with a pen", the right to express all thoughts, and the freedom of speech and publication guaranteed by law, as well as the freedom of citizens to accept criminal interrogation only in front of a jury composed of free people; No matter what case, it can only be judged according to the provisions of the law ",and so on. It seems that his understanding of freedom is not beyond the scope of British freedom. However, one thing he said bluntly according to the reality of capitalism. He said in the entry of "property" in the Dictionary of Philosophy: Society does not need farmers to get rich, but needs people who have nothing but a pair of hands and a kind heart. They will be free to sell their labor to the highest bidder, and they will use this freedom to replace their property. This shows that he sympathizes with the peasants' misfortune in order to liberate them and make them free sellers of labor. He is very frank on this point.
